Hello folks I own a 1999 Cadillac Deville and I was told by my mechanic that I have a blown headgasket...

We have tried using blue devil headgasket sealer which worked for about 1 day and then the overheating appeared again.

I was quoted by my mechanic that the job to fix the engine would cost anywhere between 2500-5000 dollars depending on the severity of the damage.

Coolant was replaced thermostat was replaced... unfortunately this did not fix the issue

I rely on my Cadillac heavily for work and I need a inexpensive fix and fast one ASAP that will last me and not pillage my bank account so that I can continue working.

if anyone has any advice on how and what I should do thanks...

If it is Headgasket I am not going to beat around.

There is no bandaid fix. Period. 

Is there coolant in the oil or is it just purging exhaust into the cooling system

Welcome to CaddyInfo forum.

The headgasket failure is very likely due to pulled head bolts.

Have you checked the purge line  on the driver side that runs over to the surge tank?

What did the coolant temp get to and under what conditions is it overheating?


Nice, clean, luxury= fine automobile
